In the production of printed circuit boards, etching is a central step in the process. This ensures that the excess copper is removed from the printed circuit board. The etching is carried out by means of a strongly alkaline solution.
After cleansing the copper surface, a light-sensitive film (resist) is applied in the clean room and exposed to the conductive pattern. Multi-CB has the latest laser direct exposures, which guarantee the lowest tolerances.
The resist now protects the desired conductor tracks in the subsequent etching process, only the unused copper is removed. Subsequently, the resist is removed by means of plasma stripping.
Multi Circuit Boards is a service provider specializing in the production of printed circuit boards in various designs. We process your circuit board - from drilling to exposure and etching to end- and impedance-control.
